Pointing at top one. Backround's extremely detaild and good looking, looks like there's a mountain behind the stock, which goes well with the backround aswell. Looks like you've taken a wallpaper as backround, dunno if i'm right but it goes well. Birds on right side fit great. The main sigshape's a bit diffrent with the roundness but it's always good to try something diffrent, and i can't say it looks bad gave you 8/10 earlier, but i'll raise it a step.. 9/10. Good job.
