Ah so many lovely arts and animations I don't even know how to put together words to describe. The animations are definitely fun to watch for sure, plus they're mesmerizing since I think I took about 5 minutes staring at each one before finally getting around to the commenting part >>
I think you've definitely improved, though, so no worries about not improving there!
If I may say, my personal faves here are June, September and October
I know next to nothing about .swf files, and yet you've put 8 moving pictures in one image. I wonder how many times you threw your computer out the window.
WOW that's amazing! I can't believe it's been almost a year since you made the Neige dress-up game, or Star on her motorcycle... feels like it was recent. Anyway, nice work throughout the years! I can't wait to see 2014 from you! :')
I think part of what makes your improvement difficult to gauge is that you're good at switching up your style with each piece of artwork. You've done everything from 3D renders to vector animations to sketches to digital artwork, in a huge variety of different colors and shading styles as well! It's really quite impressive; If it weren't for the signature roundness of your characters' features, it might seem like each deviation was from a different artist. XD Definitely not a bad trait at all - I think it's quite amazing actually.
Pft, not only can you do great regular art, but awesome animated art and your 3D art looks better all the time. Mix in that you can draw art that has a wide array of emotions behind them, and that you can complete a huge amount of commissions at a time, and I really don't think there's much to be hesitant about XD
