No problem here, I just assumed you build these things to sell anyways? They do have a certain commercial quality to them that it's only natural to put them up for bucks.
I'm always giving advice to people to do the right thing for both functional comfort of gaming, as well as resale. People think that their builds are going to stay with them forever. Which is rarely the case. People put so much personal preference into their builds and forget that at some point in their lives they may need to offload them.
Personally I've offloaded most of my projects, and while it was sad to see them go, I knew I couldn't keep them all around forever (space is a major problem on the west coast).
You said "everybody loves mega man". I replied "it should sell quickly".
Not much else to say other than it's turning out great looking! I dig the art... though if I were you, I'd clean up the lines on the sideart a bit more. Try some varying line widths, especially for the inside lines of each character. Right now all the lines are evenly sized and it makes the whole image look thick and blotchy. Keep the outlines that thickness, but the detail lines could be a few pixels lighter.
