Hello Tom, thank you so much for sharing your lovely apple drawings.
The drawing per se is excellent, very elegant and makes the viewers feel comfortable with the gentleness.
To me, though, maybe it is due to the photo reference you use, the apple seems a bit wizened.
I myself am pretty picky when selecting reference photos for my own drawings and in this case, I would have looked for a photo of an apple which looks fresher.
I once did an apple drawing with a ballpoint pen before, and maybe you can see from the reflections of the apple that it is a very fresh apple.
It is really up to what you want to express by drawing apples…I myself prefer shiny, freshly-looking apples because they appear to be more yummy, which makes me think I want to draw such apples, which choice makes me select a reference photo which meets my expectation.
If you want to make a wizened apple speak something about, e.g. maturing, then a reference photo of a less-shiny apple is the right choice.
Hope this is of any use for your future creative activities.
