In creating a character in Photoshop, I really like to stop and think of what type of character I want to create. I feel that with Photoshop, you can create any type of character and creature with no problem whatsoever, due to the amount of different tools, and options offered in the program itself. I want to create an alien like character that has somewhat of a human like anatomy. So now that I have down what I really want to accomplish with this "concept", I will go into Photoshop and try to work out this character. Keep in mind, this is a CONCEPT, it does not have to be finished and you don't have to make it perfect! Try to get something going that you like and try to be as creative as possible.
In order to get my form of my character, I will use a standard brush with about 85% hardness, and a very low opacity while flushing out the line work of this character.
Right now I am going to draw this concept from a straight on view, for a couple of different reasons. First, it is one of the easiest views to draw from, and it is a concept. I want to build from this concept later in 3ds Max and I can flip the line work over and get the same results on the left side of the character as well as the right. Some people will tell you that people and or creatures are never going to be symmetrical; well this is a concept. Draw one side of the character and use the marquee tool to cut it down the center. Erase the pixels that are down the middle and your ready to flip them over to the other side. To flip the pixels over, hit the "V" key on the keyboard which is a shortcut for move, or go up to it on the tool palette. Hold Alt and Left click and drag it over to create a duplicate of the line work that you made. You can do this step in a number of different ways, but I find this to be the best and fastest way for me. Then go up to Edit, Transform, and Flip Horizontally. Line up the pixels so that they are even, and there you go.
