Nice work on her, the dragon and the vehicle.
Don´t worry about drawing vehicles. Looks good. Bit more detailing on that,
may be.
A more reasonable scaling between subject and background would improve
a lot.

From the frame i would say it isnt resisez to 716 width... Am i right?

Interesting work!, some solid painting you've got there. I would like to see more colours in the background and those colours then used in the foreground elements. I think it might help the image.

@herrwestphal: Thanks Since the craft was added last (there were two failed tries before this one) I really didn't feel like detailing any further...
I know the background may be disproportionate, I guess I'm not so familiar with desert landscapes to pull this off right :/

@StefyARH: this is direct-linked from my own website, I didn't create a copy especially for gfxartist because I forgot how small it actually is.

@Avantis: Thanks Hmm, I tried not making the background to monochromatic by adding shades of blue-gray to deepen perspective, but I really don't know how else to do it :/

Nice colors!
