I'm not saying teamwork isn't good, but I think everyone has a different way of creating themes. Some people will like yours more, while others will find them too cluttered for a pre-release announcement of a game they're about to play. When people see one design versus another, they have the option to choose the one they like best. If we all did the same thing, we'd only have one choice, and there wouldn't be any diversity.
Honestly, I prefer the themes the way sucramjd's is making them. They're high quality, not overloaded, and last as long as they need to. I sincerely hope he continues with his own style, just like he's doing now.
Thanks for the upload. However, I'm not sure if you plan to add the following games, which are also on Teknoparrot and are missing, to another section of A-C:
3D Cosplay Mahjong
Action Deka (Action Cop)
ALESTE
Battle Gear 3
Battle Gear 3 Tuned
Big Buck Hunter World
Come On Baby 2
Cotton Rock 'n' Roll
Counter-Strike Neo
