I love it! It's size, colors, and landscaping all are looking good :) the olive green with the maroon on the ground fit very nicely. The asymmetrical shaping of the base really worked well also. Keep it up!
Not bad for a first build! There is some nitpicking to be done though. I notice that there is a large amount of studs showing in the rocks, that does look good at times, but in this case it just ends up looking kinda messy. I do like the texture of the tower, the olive green does look slightly out of place though. I also feel like some of the pictures are rather bright, but who am I to talk about that? Great job man!
