EDIT: Signature is done and was given to Worship. Here are the 4 finished versions:
This one is the original edit with a few changes.
A orange/brown color edit with the original samus color restored a bit.
A desaturated recolor edit.
This one is...different. It's a Highly sharpened HDR edit. Makes all the details pop and gets rid of depth to make it seem like samus is in fact part of the firey background. Some may like it, others may not.
The first, unfinished edit It is already sized for the forum...I find it better to post the image in the size you will see in your signature box rather than a big version that is misleading to people. Resized pictures look terrible.
