Not sure if you are a student or not but dimensions should always be based on the standard that your company has in place.
However a few things..
The dimension of 88.9 should state 88.9 SQ to indicate the tube is square and all sides are the same/equal.
Remove both of the dimension 462.2.. You are using first angle projection in your drawing so you are trying to measure a linear distance on one side of the frame member to another edge on the other side. Think about this part in your hands. How would you measure that as a linear dimension? Remember dimensions are being provide on a document so someone can make and inspect the final product. It would be very hard to measure this 462.2 dimension.
Remove one of the 640 dimensions. There's nothing wrong with the secondary one but its called over-dimension or duplicate dimension. Its like when your sketching in Inventor and it tells you "adding this dimension will over-constrain the sketch".
Also I looked at your part.. The miter ends you could've just done with an extrusion cut instead of a doing a split.
