About commissions:

I dont have a fixed priced per say but a fixed base price per case considering that every lineart or sketch posses´s different levels of difficult. 

Often the process of commissions is:

• Analyzing the piece by a quickly flat coloring to provide a base price.
• Confirmation of the flat Colors base ( and BG if applicable). 
• Shading and highlight phase, providing a small preview for evaluation.
• Confirmation of the Final price.
• Payment and send the file ( .PNG or other formart) 

Send a PM to check for availability and other information. 

I am open for art-trades too, just Send a PM to check for availability as well.
