As for some feedback on your inking, I looked at your gallery and I can't give you anything as of yet with you just starting out. Because linework inking is the basic style that relies on color work to finish the drawing.
An inker needs to look for depth & effects for the drawing that can stand out without the use of color. This you will learn as you continue to do the inking. Here is a tip that I give to all artists that want to learn inking. Go to any art shop, craft shop. And pick up anything that does black. By looking at all the different types of tools, you will notice different type of line weights and different type of effect you can get. Experiment & have fun with it. Hope this helps you, and love to see what you come up with the next inkings you do.
