Photoshop with default round brush with a bit of textured round brush for the background. 2 hours.Created for Reference:I am aware I changed the perspective a bit, it wasn't my intention. I need to shift my focus on the accuracy of colors more to the drawing aspect and be more accurate there. Despite that, I think it came out alright. This deceivingly simple study made me rethink my process because I've learned a lot from it. So hence, yes, I should do more studies like this one. And yes, I am aware that the background/ground is less yellow than the reference, but I did it on purpose to give the padlock more contrast. I don't know if it has succeeded, but it was still a good experiment.
