Eh, that fact alone should be an encouragement. IMO, artistic training is not a prerequisite to drawing and talent is a God-given gift.
Sometimes I feel uncomfortable stating that comment, lest I be thought as proud. However, I must acknowledge that God has played a big role in this and take pride in His blessings.
Actually, I did have one water-coloring class that I really hated, for it did not even come close to fulfilling my real interest. Good thing it didn't last long.
I do plan to take some art courses later on. But I've heard about some artists changing their style after taking the educational institutional route - for the worse. For example, some artists end up with a Disney-like style which for some, brings up hostile reactions.
Perhaps it helped that I learned how to develop my style on my own as I didn't have 'interfering' influences. But really, I'm not so sure.
