Here's my redline with a few notes c:
Sorry it's kind of messy but hope it works
Just would like to say, I'm not an expert at canine anatomy and am still learning so my advice is just my opinion along with my redline being my person style. For example, the ears aren't very realistic and the fur on the back of the neck is exaggerated but I hope it can still help
Also, if you want to delve into digital art, I suggest looking into getting a tablet. I would recommend wacom as they have good professional and novice tablets to help you start learning!
Hope I was of help!
