Yes, This is Official (screenshots made by the Numberblocks Official TikTok account) My opinions on the designs 41: Good enough 41's design is good on its own; the only thing I have to say is: her arms are placed to low, and the 1 block doesn't seem right on where its placed; but despite those flaws, it's okay 43: Actually quite interesting 43's design is quite good in my opinion; his (probably main) shape is a good attempt, and the arrow pattenrs on him fits in design; but I would question either the placement of the 3 block or his face, but it's fine. 44: Could've had more potential 44's design Could've worked well if A) he had an array display, and B) his eyes were rectangular (or had eyebrows) [which is something many NB fans are talking about] ; but with what we have, it's partially okay. 46: I don't fully know... 46's isn't too good, but not too bad. The only things I would say is that (just like 41,) her arms are placed too low; and also, (something I think NB fans also talked about,) Her pupils are too big. But overall, it's fine 47: okay... 47's design is actually mostly good in my opinion, I just don't like the 7 block placement on her; some NB fans said (or would say) that it looks like the bad finger [Scratch didn't want me to say the actual wording]. It would've simply worked more if the 7 block was placed horizontally instead of vertically, but it's fine..
Overall opinion: Actually could've been great, but have minor pool backs What I think: A) Someone impersonated the NB official channel to make this as a Joke B) Cbeebies/BlueZoo are running out of ideas and/or got lazy C) they want to make Prime & semi-primes numbers look more simple than composites and rectangular numbers (but didn't work too well) D) These aren't the actual debut designs, and are just beta/prototype designs E) Cbeebies/BlueZoo made the designs rushed/done last minute ...IS what I would've all said if this project was made sooner. Allow me to explain: Since about a week passed since the official reveal (which this project was intended as soon as that time, but progress got lazy and slow); I'm starting to get used to these designs, and I also think I understand why we would get used to the designs when they actually debut. Remember the backlash the NB community had on 33 - 39 (during the mathlink design leaks)? Well we kinda got used to them when we started to know more of their personality and final rendered designs. [Also, I think the Series 5 [23 - 81] and Series 7 [42 - 72] probably must've had SOME sort of backlash when they were first revealed, then the backlash faded away later when the finally debuted] Also, for 44's design, I think I understand why he doesn't have rectangular eyes and an array display (according to Videos of 44's design, and asking google/gemini): A) Circular eyes: Some numbers can break the rules BlueZoo makes or can't mix them for 1 number when making designs. Example: Some multiple of 10s (20, 30, 50, 60, etc.) Have more than 6 factors, but have circular or ovular eyes instead of rectangular. I think the circular eyes signal that BlueZoo would overlay the League-Of-Elevens rule over any other rule (even the super rectangles rule), so they decided to give him circular eyes [but why couldn't they just mix the rules together by giving him rectangular inconsistent eyes to even it out? I don't really know] B) Array display: 64 is also a super rectangle witn 7 (if I remember correctly) factors, and yet doesn't have an array display. And I think Cbeebies did this with both 64 and 44 (according to one of the videos I watched about 44's design) because they didn't want to directly tell/show the audience that they are super rectangles, because shapes like 2 × 32 or 1 × 44 are just TOO big for the show, but the audience (If they're older enough to understand, or is told by 64 (like she did in her debut) and/or 44)can still understand that they're super rectangles.
