Your drawings exhibit a lot of talent. If you aren't the best tattoo artist i've ever seen right now, you may be one day. I agree with Ronin's pointers.
I've always wondered what people really thought, and how to provoke the answer from them that they may think but never say. That is why I wanted to do that for you. Maybe one day I will ask you to return the favor.
I've been good at a lot of things in my life, however no matter what it has been, or how much I tried, I don't think i've ever been truly great at anything. Newly married with a child on the way, I am very much about being a great husband and father-to-be. I'm sure you can relate, being a newlywed yourself.
Best of luck being great at whatever you do.
