I love the SOTW entry, Edwin.
Your work is great, but I believe you should start expanding in the composition category. I believe you add a bit too much to your pieces so you have weak composition. Try to go for a more simplistic look.

For example, number two is cool and all but I believe the lens flare line wasn't a necessity and the two bright blue areas on the side of him are quite distracting.

In addition to composition would just be bringing your focal out, which again with a stronger composition would work out.

That's about all, just composition. Your FX are pretty good and your colors are nice. I'd try to move away from monochrome but in some pieces it works out well.

Keep it up!
