Creating Blood

I've tried putting blood on many of my skins and I can never do it. It always looks too bright or misshapen. If anyone can lead me to any tutorials or just tell me here I would be much obliged.

You could copy and paste from a "corpse" skin, but when you are in a paint program, I recommended not using a solid brush, or a brush with "solid" edges. Use something with soft edges for a more professional look.

Rep me up Scotty!

PS: I like your avatar lol.

Heres some bloods. I usually use them. They are good.
Open it with Photoshop.
Look at the layers table. There will be about 7 - 8 layers. To select the layer pixels
push on a layer (in layer table) and push it again having CTRL pressed down. Then just CTRL+C and CTRL+V to your image. (PS: to move layer pixels hold CTRL and press on layers pixels(blood in this example) and holding mouse button and CTRL drag it)

There are 3 blood layers, 3 or 2 wound layers that is needed.
