[outlaw] Sig Interest Check/Critique

Was messing around with creating backgrounds the other night, and came up with this sig here:

my Black & Cross fox

my Arctic & Red fox

Actually fairly happy with how the background turned out, but couldn't draw a good enough horse to go with it, so ended up using this cute base! 

Does anyone have any advice/critique on the background? I'm trying to get better at them, so any advice appreciated! I especially struggle with far away perspective stuff, so for example, I've tried makings ones with mountains or trees/forests in the background, but I can't get perspective right.

Also would there be any interest in recolours of these? And if so, any suggestions on price?

it looks great, but I would try and add some shading to the background to give it more depth, and because it feels a bit plain

@Horsegirl: attempted some shading and shadows. How do you think that looks? (would add some shadows under the horses too on a finished one, just wanted to play around with just the background first).

It looks better! ♥

Awesome, thank you for the help! ♥
