Welcome @jangelsb,
Thank you for sharing. I haven’t explored the workflow yet, but I can already make three suggestions (the last two also apply to your other submitted workflow):
You might want to consider a different name, seeing as gitx is already the name of a Git client. Not a huge deal but you seem to take care into the names you choose, so worth mentioning.
Having completely mono coloured icons won’t work great for people who use a theme which doesn’t contrast well with the chosen colour. An easy approach is to have a contrasting border colour on the icons.
To take good looking screenshots, start by pressing ⌘⇧4, then press the space bar. That takes you into window screenshotting mode. Hover over Alfred window and click. You’ll get better screenshots, including the window’s shadow over a transparent background.
