Size relationship

Here's the size relationship between Goblin and man assuming the human is 6 feet or so.
This image is another rough drawing of Paragon Greystone thats baesd off an older post. I've revised the character a bit and will do more digital revisions. I'm doing the linear drawings of these 2 character in flash and then adding colour through photoshop to see how the characters look a finished pieces. I've been debating inking them traditionally but I think that may prove to make more lengthy process for colouring. Unless anyone out there knows a more efficient way? Please share!!!
