well I'm flattered you like my illustration/concept and I also think that imitation is the sincerest form of flattery. I just wish you took the idea/concept and pushed it more in your style it's cool that used my illustration as a template but all it looks like is a copy, which is fine but I believe you can do more. You could change the pose of the figure or what and where the figure is standing on or you could frame the composition differently like moving the figure to the bottom of the image and adding more elements in the sky and so on.

Again I think you did a fine job copying my illustration,most artists get inspiration and ideas from each other all the time as well as copy select bits and pieces of their styles and images. It's important to make your own art and find your own voice, why not play around with figures and shapes and see what things you can create. So keep blasting away and making art I'm sure you will generate super cool art that is all you. Feel free to drop me a line any time you have questions on art or any thing like that.
