Hey there secretproject147,
I'm a traditional artist with lots of experience in classical pencil drawing techniques, and I've been painting in Photoshop for around 10 years.
I'm very meticulous and I take my work seriously. You can see samples of my work in my portfolio, and examples of my painting under "Painting: Still-Lifes". Note that those are digital works.
I cannot ship you a physical oil painting, but if you want a digital painting done to mimic traditional paints, I can do that.
Will this painting be done from a source photograph, or from a description? Do you have specific ideas as to the colours, the girl's pose, clothing, etc?
I look forward to hearing more detail about the project and hopefully we can do something together.
All the best,
Andrew
