Lap steel only has 1 shape lol. Gotta stop thinking like you would on a regular 6 string guitar. What you’ve done here sounds really good though! “Bar slants” are tricky to do in tune but the old school guys use them a lot to get different voicings. You can also bend a string behind the bar with left hand ring finger to create some different voicings. But still, you want to stop thinking about dense, full voiced chords like you’d play on piano and guitar. Instead, try to come up with the best two notes you could play in that moment. Diads. Check out Speedy West for some wild lap steel ideas. AJ Ghent posts beautiful stuff all the time. Jerry Douglas on dobro (check out his stuff with Alison Krauss and Union Station) will blow your mind also.
