Sin'dorei300: Needs more work, it's blurry & undefined.
Try to rework them from scratch.

Sin'dorei300: Take a look at the approv'd lightning icons in THW.

Sin'dorei300: Take a look at this and other lightning tuts.

I would suggest zooming it in to the actual object which is the Lightning. Overall, it looks good but did you do the lightning by yourself? If yes, I am happy because you are actually practicing making icons from scratch.

and what the user below suggested also.

Good, I guess. Though that lightning needs to have more forks.

Agreed with Hell Master. Also the background is a bit empty. Maybe add a bit of color to it.

I edited an existant picture, cut the part i needed, edited and colored, i did not start anew. i'll try and edit but i need a more powerful image editor first my photoshop is old

Looks like this is just a cropped and recoloured version of the Forked Lightning texture. :/

Edited to add more forks, tomorrow i'll edit again if needed

Try to make the BG darker.

i can try. i got a personal problem need more time.

BG now darker, added more color, redrawn half image anew

It looks quite off. The glow of the lightning cuts off with the main background which makes it quite bad. I would suggest providing an overall same colored BG with the color of the thunder as well but not too much of the same color. Try playing around with the same color but of different styles.

Now is it better or worse? not sure if i did something right or wrong :|

I don't know, it now looks like roots with red energy coming from it.
Maybe making it more zig-zagged like the other lightning icons could fix it.

I agree with Wolf. Here are some examples of lightning icons:

Judging from your old into this, it pretty much is worse, no offense, you'll have to take the truth in this. The light of the lightning is too strong and bright which makes your main object which is the lightning itself too undefined and unclear. The lights should be a little dark and also it's size smaller to the point that it covers the whole lightning exactly.

Good luck!

While i am working on this one, these are the icons i'm using for this thing in my map until i can make a good one
