No problem dude. I'd say drawing fusions is actually a good way of learning character design.
I'd recommend drawing a simple rough of the characters you want to fuse. Learn the shapes of their designs and such. This bit teaches you how other artists draw and design their characters.
To start fusing try drawing their three different eyes and see how each is made up of different lines or shapes.
One is a pure circle. one is almond, and is one is a oval.
Fuse two together and see what you get.
After fusing shapes, don't forget the personality of the character. How they stand/pose and their expression.
Play with it a while drawfriend, hope this helps.
