The shape is right with the carrot profile.
Top one looks like a cased caddis and the bottom one a net building caddis.
Just make sure the colour of the material you use is similar to the substrate of the water and surrounds, although there are definitely variations that lean to a cream colour of the caddis!
Your body material looks like it would be able to take coloured marking pens like light brown, tan, olive green (my favourite) etc. With a bit of coloured ink, you're able to open up a whole new world with this as you continue your tying.
Make sure there is a bit of under weight to get the fly near the bottom too.
Fish them with confidence.
Good luck.
