I think it's great, too. Nice and subtle, just the way I like it

A wash would help bring the details of the clothing out, which could help, but as far as the pattern goes I can't see anything wrong. It doesn't look right because it's being painted on 28mm?
As for picture resizing, just google it. There is at least one (and probably 10+) browser based, no login site for resizing

Cheers for the colour pallete, I will be painting similar camo soon and I'm reluctant to start as well.
