@Joy-Heyer If you are going for a more designed approach, I recommend losing the correct "perspective" step. There is no need for it, and it can actually hinder the process. Once you decide to go for the wonky look, you need to make sure that lines aren't converging to a vanishing point and that all the details are "off" by the same amount. It's actually much harder than people think!
The important thing is shape design. For this look to work, everything needs to be re-designed in the new style. Make sure big, medium, and small shapes are all working together. Design is the most important step in making an image like this work. I often tell illustrators to go study graphic design. I think that training is often lacking in illustration study because we, as illustrators, are so worried about being able to draw well (at the expense of design!). I think good design beats good drawing any day.
Keep it up! I can't wait to see more from you!
