@poster,
I'm some sort of critic, so here's what I think. (Fortunately, the criticisms I do are of the constructive type.)
1. I think you have a lot of flair with the tools you use: Photoshop (obviously from the brushes you use), and perhaps CorelDraw. Your 3D text abilities are also great.
2. (Spin-off of above) Knowing how to use a tool is not enough. Creativity has to be added. Questions u should ask yourself include: what sets this design apart from others? Have I see stuff like this before? What are other people doing?
3. (A spin-off of 2 above) To some extent, u seem isolated. Do u watch other designers? Do u take interest in them? Do u see d works of your contemporaries? Are there graphic designers around u who challenge u with their work? If not, then u're isolated, and this is not so good. Inspiration and challenges come from seeing other designers, and if there are bad ones around u, then u'D suffer from the one-eyed-man syndrome.
4. Color. You seem to love color so much that it gets in your way. Most of your stuff are so colorful that they are too colorful. Perhaps, it's time for you to break away from swatches and experiment with white. Try white backgrounds and use your colors in d foreground. these days, white works wonders (www).
5. Fonts. From the works I've seen, your seem to lack creative fonts. Some of d stuff u did might av been much more better if u had used certain fonts. A designer without a good font collection is in big trouble. Anything between one thousand and three thousand fonts is okay, provided there are lots of diverse and creative ones in there.
6. lastly, learn to let go. Design can sometimes be therapy. Breathe in, and exhale. Be easy on yourself. Hold your mouse like a painter holds his brush, and like the brush goes, move with flair. With design, learn to express before u impress. Express your interpretation of the work, before u av it in mind to impress your client. And above all, be subtle. Subtly works wonders.
7. One final thing: from a design, i can know the type of person d designer is. your colors and rowdiness points to some internal trouble. Is that so? You might want to resolve those issues inside u first, or put them aside when u're designing.
Design is much more spiritual (not religious o). Ask the French.
Cheers.
(here's a site i think you should visit.
http://www.thefwa.com It's actually a site that showcases the best websites of each month, but the web designers are great graphics designers. Be warned though: these sites might intimidate u and make u despair in your skills. But don't worry: always remember that we are all constantly learning, and one day, we'D be just as good!)
