Great exploration! Lots of fun expressions in here, awesome job!

Yeah, I would agree about the Mcburnie scene. It has beautiful use of line, but it's rather difficult to make it out for its own study given how well it's integrated with the rendering. As for Ivanova, the study is quite close, but there are a few notes I think can help: - The line weight is used most heavily around the areas of emphasis. You applied it properly for the area around the face, but you can also notice it in the original for the toes grabbing on the branch and the fingers grabbing the fruit. Having not just one place to center the attention helps continue the flow throughout the piece, avoiding a static focal point. - Ivanova's use of strokes for fur detail is very economical and distinct. With rare overlapping, each stroke feels very purposeful and intentional, and the simplicity prevents weighing down the drawing or creating unintentional focal points. - It's a very masterful piece for line flow, and I think warming up with line quality exercises beforehand as seen here https://www.proko.com/s/iu1Q can really help loosen up a bit and get closer to that level of fluidity. Of course, it's not an overnight thing to achieve, but every practice session helps.
