I don't think that your wave i is correctly proportional in time vs wave ii (more than 3 times size, = not same structure/degree). Wave iv took less time than iii.
Not attacking, just my opinion on the count. I'm not an expert, but I'm also not using EWI school EW. (Constance Brown does mention time proportion though, I guess EWI would too)
Silver does look good though. Specially if you chart it using the SLV chart data (leaves out overnight, outside NY session bars) or just using daily bars high and low in order (lots of lower liquidity intraday noise, doesn't necessarily represent the correct wave count, at least according to Glenn Neely's methodology).
