If I may..
You're getting some good advice as far as to keep plugging away, keep trying. You're walls aren't 'bad'. I don't see 'you' yet. I just see some wallpapers. I believe that as you keep trying you'll fall into your nitch as you develop the style that works for you and best shows what you want to express. That's when it will click, happen, or fall into place for you.
Even when you find your groove, you may not get the ratings you want..that's when you have to be able to do it for 'you' and because you love to do it. But there will be folks who 'get what you're doing' or just like your style. It's the comments they leave that will make up for everything else.
Now if you want some comments, for what hey are worth coming from the likes of me....
Season's Greetings - Lose the 'fuzzy' border..bolder glassier text or No text at all
Storm Tossed - off kilter, makes me wanna toss
Broken Light- - I think the drop between this and light is self explanatory - too much. It was fine the way it was in Light.
Undefined - I like it
Blue Bamboo - I like it
Eye of The Storm - for me..very Bryce and I'm not big on Bryce. That moon is bugging me to.
Not Me - Were you going for the 'Primitive' look? Close, but very grainy. I think you were on to something here. I like the 'attempt' but not the end result.
High Lake Sunset - Nice, but for the water (IMHO) What do you work with? If PS, I might have toned down the ripples or hit it with a Smart Blur (+3, +24) I like the colors and it all blends well. (Better than Eye of The Storm)
Well, hope I haven't pissed you off or anything. I look forward to seeing more work from you and watching you develop.
