Hi.
Your works are very appealing to the eye. Especially in terms of colors. I do not have further comments on your current style. You seem to have executed them perfectly.
Though, just as what I usually say, you might want to try other styles or even develop your own. This style that relies on effects stocks are indeed nice but they have been already too common and by and by the originality of this style is gradually degrading. There are different styles out there. There are even styles that are yet to be discovered. Try experimenting, imagine more, I won't say practice more for you have been GFXing for 2 years already which is enough for a person with an interest in art to master the basics instead I'm gonna say: "Create more." ^^
That's all for my short comments on your tags. I'll be expecting for different styles in your next updates. ^^
-Maria.
