I simply stated you should not base your works on what other people want to see.
Good, then nobody will want to see it at all, then what is the point for posting it up on the forums? lol.
Anyway, here is my crit.
If I where you... I would put down the tablet and photoshop and corelpainter all the digital crap.
Got paper, cheap watercolors, and made (If you claim to be an artist) at least 50 paintings a day, FROM LIFE ONLY.
There is no need to draw conceptual or fantasy things if your artistic level doesn't have the fundamentals.
I would, if I had free time, read the philosophy of real artists like Michelangelo, Repin, Surikov, Frazetta(illustrator). to understand why real artist can't paint what he or she wants.
I would develop my own deep phylosophy basing of the great phylosophers to have power in my conceptual works. And then, looking at my work, people will think that I do what I want, not knowing that I do what people NEED.
That is what I would do. And by the way, an artist is 1% of talent and 99% of fuсking hard work.
Hope this is usefull, good luck my friend.
