It's a great first try, i've seen a lot worse but you've made a few basic errors. You don't have a border, I know I know, it seems silly but even a 1px white stroke on overlay would improve the sig. Shadows on text tends to be a no go as well, again, a stroke or just left as-is with some filter effects is fine.
You've done a decent job at 'blending da rendah' but as has been said it looks squished so make sure when you're resizing that the proportions are locked or if it was the original render that was squashed, find a new one.
Finally there's a great deal of contrast in the background which in this sig doesn't look too bad but as a personal preference I'd suggest to stick to either dark or light rather than a mix of both, it can look messy when not applied right, however the exposure on the render compliments this somewhat so it's not as bad as I may have made out.
Hope I've helped
I know it's not great, but oh well, for my first is it ok? Please leave some Constructive Criticism, thanks.
