I think Pity was referring to Mishisato providing his own work to the site. Anyways, your style is fine, since it stands out from other styles like Tennkoma or tunusa.
Yes, Gitami is right. Just keep at it and you'll slowly improve. I only began using my tablet a few weeks ago and at first I was very frustrated by not being able to draw anything. But I kept trying and learning tips and tricks from other artists until I started getting results. Spend a lot of time observing real life photographs so you can learn how light and shadow and colors work. Artists know these facts and simplify them for their works, especially in anime. Basically, before you get get started drawing yukkuris and anime, learn realistic human anatomy and after that drawing yukkuris will be a piece of cake. There's lots of good art on places like Pixiv and DeviantArt. Spend some time getting inspired by good artists and try to work while you still have that inspiration. If you're having a bad day the art probably won't be too great and you'll get discouraged.
I havwe actualy found that sometimes, just studying artwork itself, to figure out how it was done, can help one to develop a style. (I dont have a tablet, or any decent drawing material, so I have not got any way to develop a style for myself yet, and I cant go out and buy one as I am saving for my holiday in july)
>>i wanna draw too but...i'm not good enough ^^" LoL, me too... I'd introduce "Cattle-kkuri", the Steak Filled Cow Yukkuri that's there to be eaten. And survives on lawn trimmings. (I like cows.) My friend and I had a lengthy chat on what a Cattle-kkuri would act like :-P
Anyways, SUN, I like your arts, but they're a tad gruesome for me :-( I just kinda wish that the Yukkuri could occasionally come out positively at least every once in a while, or at least neutrally, instead of just rape and death. /o.o\ As for critique... I'd say sometimes the outline lines for the hair and mouth and such look a little too thick at times, like in Marisa's hair (like when she's putting on her hat) Outside of that, I'd say it's alright.
I like to imagine Makako's, Nako (back when he/she used to draw yukkuri... before violent edits of his/her work made them stop), and Clammbon as my #1, 2 & 3 favorite artists... so I kinda compare you to them. (Just so you know what I consider as an ideal yukkuri pic) Your pics seem to be aiming for a more... "Realistic" look for them though (at least the colored ones are), so I'm not sure if they apply to you. I suppose I just like My yukkuri looking Cartoon-y
