Thank you for your comments. I give really importance to the shadows in my drawings.
I have more and I'm constantly making new ones!!
*dst - I will search for him then, and see what he thinks thank you!
*gonzalo - Thank you sir!
*Neno - Thanks, you will. I already have lots made so I just need to upload some of them.
*Aeoshattr - Thanks a lot *smiles*
*Change - If you put your mind to the task you'll get results before you know it. I trained with ramdom objects and pointed a light in the direction I wanted, that way I could understand how can I work with shadows
