Nice little WW1 fighters - if you want to try some more there are 1/72 aircraft for download at Landships II -
Landships II.
Wayne McCullough took a break from his usual armour models and designed a Halberstadt CL II, Junkers J.1 and a Short 184 floatplane. There's also a Zeppelin model by Thorstein Brand if you feel like a real challenge.
