Thos tools (like magic wand or magic eraser) use the difference in tones to detect the shape, so if parts of your artwork are cloe in tone to the background, it will not work.
You can try a few other things, that may - or may not - work... Bar that, you'll have to use the pen tool to trace around the artwork amanually, and convert that path to a selection ...
Things you can try:

object selection tool. It tries to detect the outlines, but in a less crude way than the magic wand and magic eraser do... The settings you choose at the top are important:

you can also try
"select">"subject"

there are no settings, so it will generate a selection of what photoshop think is the subject.

There are other methods but they won't be suitable for your example, as they will work, again, with the differences in tone.

So as I said, if none are satisfactory, I would go to the pen tool and manually trace around the subject. At the very least for the white parts. What you can do is use any of the other method if they produce good results for the non-white parts, save the selection (as a mask or as an alpha channel), trace around the problemeatic areas manually with the pen tool, and add those new selections to the mask or alpha channel.
