Please do not take this wrong....this is going to be a helpful and constructive opinion!

OK, here's the problem that we found with PVC like that......
Look at pictures of Crappie in cover....The cover they like is dense, and they can move around in it, or it provides shade, ambush points, supports bio diversity, draws forage, etc.
To really allow the Cover you built to be used, you will need to add at least 5x as many small PVC "branches" to the main trunk, or put plenty of same height trees or limbs directly beside and around it...this piece of cover alone really offers nothing except the Base trunk!
To build good Crappie cover you have to understand what they prefer....Big Stumps, dock posts, downed trees, root systems, tree tops, etc., this is what you have to provide for them to be effective.
Then you have to decide how many fish a single piece of that cover will hold, then you build an area to hold a certain number of fish, and build multiple areas if needed....then if you want your areas to replenish themselves you have to build or put in cover for spawning, minnows/baitfish/ fry, craws, and micro-organisms. This gives you a self-sustaining ecosystem!
