When I saw this..
...I had to write a review!
Seriously, you need to do something about this. You are far too talented not to show off your incredible work. As a slave to making art myself, growing up I almost resented when people would tell me I needed to go into an artistic career or that I was "going to be an artist when I grow up." Yet here I am telling you this.
Anyhow, for an actual review, I will list things I like and don't like.
-The detail! Holy crap! The sheer amount of detail in your colors, the textures, and the composition is brilliant, and clearly took a lot of work.
-The colors are wonderful, dramatic, and capture the mood well.
-I have seen fire in real life, but have not seen lava, although you portrayed both of these with what I would call pretty close accuracy -- not the easiest for some.
-The mood is great; I think everyone who looks at this can see more than a character on a white background, or an image with no story or emotion behind it. You did this well.
-There is a lot to look at! It's very interesting to the eyes, and I really appreciate the brilliance of it.
I don't like:
-How there are not more of these from you! You must make more..
..but seriously, you are very talented. Don't let this go to waste! That doesn't mean you need a career in art or anything, but just don't stop doing this because clearly you attract a lot of positive reactions from people for it -- you are captivating! Great job!
