Sure, one thing I would commend on is that I wouldn't call your W1 correct. Mainly because it's still part of the declining structure (within it's trendline). I would relabel it as a failed W1/W2 or simply put W0 where your W2 is (I think both labels would be correct). Also there's a problem with the size of W3 relative to the W1 you are using. W1 is more likely from where you labeled "(2)" to the first triangle you have (the 103 high). W2 is a also a rising wedge. I should note however that I look at wave theory very differently than most EW traders. I set my projections differently also so my counts tend to look different but are still accurate in general. Here's my chart:
I like your W4. I count waves in an odd way, so with my count that would be a higher degree WB into a higher degree WC. Technically it's not correct Elliott Wave theory except I am using the underlying psychology behind what defines a wave structure. It has to do with a property of corrective structures that I discovered years ago.
