I think the blocks are lovely and your workmanship fine...but I am guessing that what is bothering you is that many of the fabrics are very similar in pattern and "value", so they all look the same and you don't feel as engaged with the quilt.
To create interest and draw the viewer in, a composition has to have contrast to it. In the classic and very simple red & white quilts, the contrast is simply the contrast between the red and white, which is very strong. So strong that no matter what the block is, the quilt is arresting.
To add contrast, you can:
-change the colour range...experiment with opposites on the colour wheel ie. you have all blues here, how about a punch of orange (which is the colour across the colour wheel from blues)
-change the values...you are using cream/white triangle centres, mix up the intensity of the blue batiks, attempting to use very light, very dark, and something in between
-change the blocks...mix your very angular triangle blocks with blocks with curved elements...or work in solid blocks (no pattern/piecing)
-change the scale...make a mix of sizes of your chosen block...some very small and one really large!
If you search "triangle quilts" on pinterest you can have a look at how other quilters added interest to a simple block pattern.
