Thanks for the comment, i thought i could help you out a bit on what you can improve on this wall :)
1. you need to work a bit with the extraction, you still have pieces from the green background left on rekka...
2. the bg is very bland; doesn't look like you've put much work into it even if you've done it entirely;
and large blank areas should be sparse since it's really hard to use them correctly, this is an example...
3. the colour of your bg doesn't really match the colour of rekka; or the other way around, depends on how you look
at it ^_^'
well, it's about that, otherwise good work :)
