WellI’m not sure how many of these suggestions will apply, since I don’t know how much you’re trying to resemble it but…
the feet on the bottom of the lamp are very strange, and not in a Dr. Seuss way, I would suggest making them look like the lamp has 4 feet, and they are just strangely placed and skewed. Overall, I think the whole base is too rigid, it should look much more distorted to match with the feet. Because the pole comes off at an angle, the whole base should stretch that way like in the reference.
the trim as the pole goes up, I really like it, except for the first part, the part that looks like a ufo, I hope you can tell wich one I’m talking about, but it sticks out too much, I would try to model more smaller ridges
The lamp shade is perfect, I would suggest adding the ornament on the very top of the pole though
Overall,this already has a great cartoon, Dr. Seuss feel, so liek I said, I don’t know how far you want to go with it, the base is the only thing that really stands out as not matching the style though, the other comments are just details you may or may not want to include…
Really neat though, you’ve inspired me to do something cartoony.
