I don't want to piss you off, and I kindly give you some advice.
If you want to make a great avatar and siggy, you have to look at :
1. The picture, I mean, more colourful are better and high quality is better.
2. The meaning of your siggy and avatar
Sometimes, they cannot describe the true meaning of what they make, that's why the result is going worse. You have to know the reason why you make that picture.
3. Note that, in internet rating, they rather choose that more effects you have, it is better. So, try to using different effects and try to experiment it.
4. Someone's picture, why he could make that picture better than me. And then, try to experiment to it, that's is the only way to become an expert photoshop. See and Learn.
Okay, from what I saw from your avatar and siggy, you are using :
To siggy perpective :
1. Using 2 sprite that are colourless.
2. Using 1 monster background without any effects.
3. You are using blending mode, am I right?
You are using blending mode to :
1. Monster background to monster sprite that are colourless
2. Monster background to Starcraft II logo
To avatar perspective :
- You just crop it from siggy
- You add BAKU to it.
So, this is what I recommend :
1. Remove the colourless sprite. If you still want to use it, just make it more transparent.
2. Try using more effects to it, from which effect you know, one by one, try to use it
3. Starcraft logo no need to blend with the monster background. Instead, just make it normal and add some effects to it. For example : Try using icy effects to Starcraft II, nice huh?
4. For the avatar, try just crop the monster background, it is better.
Nah, I have 1 background that might inspire you to do better. This background is from my 6th project of photoshop.
You could ask me via PM or MSN if you are still not understand or still have some unanswerable questions.
I rate you : 7/10 and my answer is : Yay!
