Looks normal, for an engine without any load on it.

Just FYI: For viewing sight glasses properly, you need to position fuel line/clear tube and watch the fuel "going uphill" in those lines. {Don't be fooled by any stagnant air bubbles sitting in some horizontal piece or downward piece of clear hose.}

Your hoses aren't too bad; personally,I would have made them a little longer, just to get some more area of "Vertical flow" to view.

 On longer hoses, we will lift the hose, to remove any stagnant air bubbles, right before testing, then lay down how we want, for viewing and then test, from there.

Here's a diagram, of what CAT puts in there literature, for one of the sight glasses that they sell:
