Welcome to the Anatomy Forum.
Frankly, you may hear differing opinions here as to whether or not you should draw / paint from photos, but I’m personally for it, and think that working from Reference is far and away better than not working at all.
We happen to have a great ongoing Workshop series in which anyone may join / leave at any time:
Here is a list of all Open Figure Drawing Workshops.
OFDWs run every 2 weeks when we are working from photographic reference of a model, and every 4 weeks when we are working from Master Painting Reference, as we are currently in the latest OFDW:
Open Figure Drawing Workshop - Rembrandt Master Copy - with Rebeccak 016
You are welcome to join in! We are currently nearing the end of the 2nd week of a 4 week workshop ~ meaning there are 2 weeks left to go, plenty of time to participate.
You should also check out the great work that has been produced in previous OFDWs here in the SPOTLIGHT Forum:
Links to all Open Figure Drawing Workshop SPOTLIGHT threads
In past OFDWs, we have used reference from the really great sites:
www.characterdesigns.com > go to Photosets

Looking forward to your participation here on the Anatomy Forum!
