comic style coloring

I am trying to learn how to do good comic book sketching in the gimp and Eldron made an awesome image i just had to color in for practice. I would love some advice on technique etc. This is only my third comic book coloring so bear that in mind. Oh and Eldron if you want me to remove this let me know.

for good tuts/tips on comic coloring check out polycarbon, they have some great examples and line art for you to practice with.

ermmmm you should do it with layers and make each layer a Multi for blending mode. so you wont need to paint over lines
